ANCHOR OR TIE FOB, LOOP ENDS.

Application filed May 19,

7' 0 n7] whom it may concern Be it known that I, GEORGE D. SLAY- MAKER, a citizen of the United States, residing at Detroit. in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Anchors or Ties for Loop Ends, of which the following is a specification.

This invention relates to anchors or ties for loop ends. It has for its object a 81mple device of this kind in which the loop ends can be laid and the two parts of the anchor driven together to bite into the cable, rope or other linear member that forms the loo li oops are very commonly used in connection with braided wire cables, especially in connection with electric street railway overhead equi ment. These loops are now ordinarily mare by unbraiding a part of the cut end of the cable and serving the wires around in opposite directions. Usually there are several of these wires and inasmuch as they are stiff and heavy, it is a rather diflicult and time-consuming operation. It is the object of the present'invention to provide an anchor which may be made simply of two pieces or blocks into which the looped ends may be laid. The two blocks may then be driven together and after the teeth in the blocks have bitten into the cable and the cableis put under tension, the more tension brought to bear on the cable the harder the teeth will bite into the cable and the tighter will the blocks wedge together.

In the drawings,

Fig. 1 is a side elevation of the anchor applied to a chble.

Fig. 2 is a cross section on the line .22 Hf 2, t Fig. 3 is a perspective of one of the blocks.

one end. namely, at the point 5, and wide at the other end at the point a. This afi'ords an inclined dove-tailed track a". This block is provided at one side of the center of the main groove with a groove 0? of semi-circular cross section provided with teeth and in this is adapted to be laid one of the loop ends. The other block is provided with a pair of overhanging upper edges or dovetailed tongues e which have tapered under surfaces f complementary to the inclined,

track of the dove-tailed groove in the block a. The male block it is provided with a toothed groove 9 at one side of the center in which one of the ends of the loop may be laid. These two grooves do not register when the two blocks are assembled together, as is plainly shown in Fig.2. Each of the toothed grooves is opposed by a plain surface of the other block.

Take the showing in Fig. 2, assuming the is laid into the toothed groove 61 of the fe-' male block or section a. The two blocks or sections are then driven together. When the cable or other linear member is put under tension the main run of the cable which is designated 7 will pull toward the viewer. F

it toward the viewer. Now viewing Fig. 15

it will be seen this will be an efiort to pull the dove-tailed tongues up the inclined track and simply wedge the two blocks or sections together tighter. Similarly the tension on the loop end 2 will he in the oppo site direction and inasmuch as it has only the teeth of the female block :or section a biting into it, it will tend to pull the block a away from the viewer, but an inspection of Fig. 1 will show that this will simplydrive the wedging blocks or sections more tightly together.

In the form shown in Figs. 6 to 9 inclusive the same principle of operation is employed but the clove-tailed grooves and tongues instead of being located, the grooves all on one member and the tongues all on one member. are located one groove and one tongue on each anchor section, and instead of solid blocks into which a toothed groove 'I his is nicely shown in Fig. 9.

is cut the groove is formed by a depression pressed into the metal. This permits the sections to be stamped. which is of course, =1 somewhat cheaper operation than constructing the anchor sections as shown in Figs. l to 5 inclusive, where machine Work is required on the grooves and tongues.

To be more sreciii each seetion 1n the modlfi ation shown in Figs. o to 9 IS a.

Hstsmpinghaving a section in :1. rough angle iron formation with one edge turned over 10 for-m a hooklike member in and the other edge turned over to form a flange or tongue The hook-like member in tin-ms a groo e which is inclined from one end to the other. The flange or tongue in is also inclined from one end in the other at an equal angle. The depreso is ressed in the angle iron section 'zthtl PI'OVi ed with teeth It. This is adopted to reeeiee the cable which engages in the toothed groove formed by the depression; The die sections are right and left hand, hence separate dies are required for each section as one section has the tongue wide jet one end and the groove narrow while the other section at the same end has the tongue narrow andthe groove wide.

These rooi es and tongues are essentially dove- ?tiiled groores and tongues and do not ditfer tron-i the principle of the anehor secticin shown in Figs. 1 io fi inki-lusive except that the present design lends itself to stampwedging relation. the two said sections pr! vid d with two sets of opposed smooth and toothed surfaces whereby the linear membersengiige between these two sets of surfaces and tension inopposite directions will tend. to draw the sections together when la d in the proper set of opposed surfaces 9. Ah anchoror tie for the purpose spe ified, having in eomhinat'ion. 2 mole and l emole section baring groove and tongue wedging engagement, the so id sections hav ing two sets of opposed snrfiices, one of the snefoees of which is smooth and the other toothed whereby when the sections are driven together and the pair of oppositely-tensioned linear members are. engaged between the sertions the said linear members will tend to draw the sections together when laid in the proper set of slots.

3. An anchor or tie for the purpose specilied. havin a pair of sections provided with dore-tailerl grooves and tongues having inclined surfaces that wedge together and having toothed groores at opposite sides of the center of the sections, the toothed groove of one section opposing a smooth surface of? the other block. I

4. An an hor or tie for ihe purpose specilied, having a pair of anchor sections in the form of angle iron members provided at one side with; hook-like turned-over member forming-ran inclined dore-taile'dgroore and at the other side with a turned-out flange having a 'lon'gitndinally inclined obl ge, said flsngeforming a sor -mired tongue. and ton r es and grooves adapted to interlock in wer. ging relation and enga e with a cable.

5. An anchor or tiefor the purpose speciffielch' cornpl'fising a 'psir of anchor sections eioh comprising an ember of angle section "having at one cage tnrned over hook-like formation forming a dove-tailed groove having anindlined' bottom and At the other edge turned iipto tom; a fliin'ge or tongue with an inclined edge. the tongues and ghoojves oi the ti vo members interlocking in wedging relation and each of the sections provided with o depression or groove for holding the cable, the skid depressions or grooresfii hen the ser tio ns are interlocked together opposing n plain surface of the other section.

6. An anchor or tie i o'r thepurpose specified. conprising a pair of angle section members comprising a turned-over edge forming n hook-like formstionnnd constituting a dovetailed groove with inclined bottom. the other 'edg oi the angle section being; turned up into a flange or tongue with an. inclined edge. the tong es find grooves of the two angle section's seine arranged to slide together in Wedging 'relsiion. each of the sections bein provided nenr the iingle in the angle member with a depression to term a toothed groove. said grooves or the twosections when the same are seeflidtonether opposing a lain surface on the opposite section and arranged "ea h groove to hold :rczihle for the purpose specified.

in testimony whereof I ailix nrv sig'nhture.
